The Minifit XL looks like any other laptop stand until you add the USB powered fan by slotting in to the perforations. Then it delivers a cooling blow to those places your laptop gets hottest. Makers say the stand takes laptops up to 15 inches and can also double up as a book stand, though I have never found books to get that hot. [Redferret]
